Mapping DNA sequences in a human X-chromosome deletion which extends across the region of the Duchenne muscular dystrophy mutation.


Journal Article

A somatic cell hybrid has been constructed and characterized using fibroblasts from a phenotypically normal woman who possesses an X chromosome with an interstitial deletion of the short arm. High-resolution banding indicates that the deleted segment is either Xp22.13-p11.4 or Xp22.11-p11.23. Southern blot hybridization to previously mapped DNA sequences confirms that the missing segment of the X chromosome is a deletion and not an interstitial translocation and supports the cytogenetic interpretation that the deletion extends proximal of Xp11.3 and therefore probably comprises Xp22.11-p11.23. Three further DNA sequences have been localized to the region of the deleted segment. The following order has been assigned to the seven probes used: Xpter-RC8-pXUT22-(OA1,C7,M2C)-L1.28-RD6 -Xcen.
